Is Precognition Possible?

However, the real contribution of this paper isn’t even these statistically significant results. Instead, it’s Bem’s attempt to create rigorous, well-controlled tests of psi that can be replicated by independent investigators. Because here is the dirty secret of anomalous phenomena like telepathy and clairvoyance: They’ve been demonstrated dozens of times, often by reputable scientists. (Bem is an extremely well-respected psychologist, best known for his work on self-perception.) Why, then, do serious scientists dismiss the possibility of psi? Why do rational people assume that parapsychology is bullshit? Because these exciting results have consistently failed the test of replication.
